Abstract

The present invention relates to an arrangement for connecting antennas to ports of a transceiver unit in a base station. By using two circulators and a four port sputter a more flexible small base station is attained. The arrangement provides, at a low extra cost, the capability of adding an auxiliary transceiver unit to the base station.
